BEIJING: One year after creating the food safety lock, which has become popular nationwide, the Xuhui district Market Regulation Administration in Shanghai has introduced guidelines on its use and manufacture.Similar to a luggage tag and secured around a carrying bag, it has to be broken to be unlocked. The disposable lock is intended to guarantee that food is not tampered with during delivery from the restaurant to the customer.
“It’s like putting a safety belt on the meal box,” said Zhai Hengyao, an official with the district administration.
